Application and performance Jig/Jigging machine/Gold jig/Gold jigger
Jigging is one of the relative new methods for gravity concentration. As a rougher or cleaner device, it is widely applied on the separation of gold, tin, tungsten, titanium, hematite, coal and other minerals due to its high processing capacity, large range of separation size and simplicity of operation and maintenance.

A traditional jig is mostly driven by eccentric circle, its jigging pulse curve is mostly sine wave, the upward or downward flow rate generated by the diaphragm movement and action time are almost same, therefore, it is not conductive to jigging bed dilation and stratification according to the proportion of mineral particles, and affects the sorting ratio and recovery of equipment.

Saw-tooth wave jig is a energy-saving gravity concentration device which is based on the traditional jig according to the distribution rule of jigging bed theory, its jig pulse curve likes the saw-tooth waveform which makes the upward flow faster than the downward; The upward flow time is short, the downward is long, which overcomes the shortcoming of upward flow, downward flow and action time produced by the sine-wave pulse curve, enhances the loose degree of the bed and alleviates the inhalation effects, then the heavy mineral particles in the ore are fully settlement, which enhances the sorting ratio and recovery of equipment. Compared with the sine-wave jig, the recovery of Sn increases 3.01%, W: 5.5%, Pb: 1.63%, Zn: 2.04%, respectively; Water consumption is reduced by 30%-40%, site area is decreased 1/3, the stroke can be adjusted, dragging by the electromagnetic adjustable speed motor makes the pumping speed can be adjusted endlessly. Its performance reaches the domestic advanced level; It is one of the ideal energy-saving gravity concentration equipments.
